Final answer:
The layers of the Earth from inside to outside are: the Inner Core, Outer Core, Mantle, and Crust. The Inner Core is solid and the hottest part, the Outer Core is liquid, the Mantle surrounds the outer core and the Crust is where we live.
Step-by-step explanation:
The structure of the Earth can be divided into four major layers. From inside to outside, they are:
the Inner Core
,
the Outer Core
,
the Mantle
, and
the Crust
.
The Inner Core is the hottest part of the Earth, and it's solid. Just outside the inner core is the Outer Core, which unlike the inner core, is molten or liquid. The Mantle surrounds the outer core and is about 2,900 kilometer thick. Finally, the Crust is the Earth's outer skin, where we live.
